Abstract (en)
[origin: WO2005024707A1] A face recognition system comprising an image sensor (100), the output of which is fed to a detection module (102) and the output of the detection module (102) is fed to a recognition module (104). The detection module (102) can detect and localize an unknown number (if any) of faces. The main part of the procedure entails segmentation, i.e. selecting the regions of possible faces in the image. Afterwards, the results may be made more reliable by removing regions which are too small and by enforcing a certain aspect ration of the selected regions of interest. The recognition module (104) matches data received from the detection module (102) to data stored in its database of known features and the identity of the associated subject is forwarded to the output of the system, provided the "match" is determined to be above a predetermined reliability level, together with a signal indicating the level of reliability of the output. The system further includes an analyzer (106) and, in the event that the level of reliability of the output is determined to be below a predetermined threshold (set by comparator (108), the output of the detection module (102) is also fed to the analyzer (106). The analyzer (106) evaluates at least some of the data from the detection module (102), to determine the reason for the low reliability, and outputs a signal to a speech synthesizer (110) to cause a verbal instruction to the subject to be issued, for example, "move closer to the camera", "move to the left/right", etc. If and when the reliability of the output reaches the predetermined threshold, this may be indicated to the subject by, for example, a verbal greeting.
